Weekly investment from mining rewards, without getting destroyed by fees?

Wanting to spread my mined RVN around a bit, and was thinking to do it weekly. I now realize that depending on coin/token, I get absolutely destroyed by fees when doing a wallet to wallet exchange via changenow.

Is there a smart way to diversify mining gains? I manage about 1500 RVN per week on my setup, and I was thinking to spread it 4-6 ways, BTC/ETH, metaverse-stuff, stablecoin interest/staking and then of course keep som RVN.
